Section 13.2 says:

 -dct_cat1, -dct_cat2, /* cat1 =  "111100",
                                  cat2 = "111101" */
        18, 20,
         -dct_cat3, -dct_cat4, /* cat3 = "1111100",
                                  cat4 = "1111101" */
         -dct_cat5, -dct_cat6  /* cat4 = "1111110",
                                  cat4 = "1111111" */

It should say:

 -dct_cat1, -dct_cat2, /* cat1 =  "111100",
                                  cat2 = "111101" */
        18, 20,
         -dct_cat3, -dct_cat4, /* cat3 = "1111100",
                                  cat4 = "1111101" */
         -dct_cat5, -dct_cat6  /* cat5 = "1111110",
                                  cat6 = "1111111" */

Notes:

The last two bit strings are for categories 5 and 6; only the preceding one is for category 4.
